At present, various CPU register macros that refer to CPUACTLR are named
ACTLR. This patch fixes that.

The previous register names are retained, but guarded by the
ERROR_DEPRECATED macro, so as not to break platforms that continue using
the old names.

This patch uses the U() and ULL() macros for constants, to fix some
of the signed-ness defects flagged by the MISRA scanner.

This patch makes all the defines in the CPU libraries unique,
by prefixing them with the CPU name.

NOTE: PLATFORMS USING THESE MACROS WILL HAVE TO UPDATE THEIR CODE
TO START USING THE UPDATED NAMES

ARM erratum 855873 applies to all Cortex-A53 CPUs.
The recommended workaround is to promote "data cache clean"
instructions to "data cache clean and invalidate" instructions.
For core revisions of r0p3 and later this can be done by setting a bit
in the CPUACTLR_EL1 register, so that hardware takes care of the promotion.
As CPUACTLR_EL1 is both IMPLEMENTATION DEFINED and can be trapped to EL3,
we set the bit in firmware.
Also we dump this register upon crashing to provide more debug
information.

Enable the workaround for the Juno boards.

This patch adds cpumerrsr_el1 and l2merrsr_el1 to the register dump on
error for applicable CPUs.

These registers hold the ECC errors on L1 and L2 caches.

This patch updates the A53, A57, A72, A73 (l2merrsr_el1 only) CPU libraries.

This patch adds handlers for dumping Cortex-A57 and Cortex-A53 specific register
state to the CPU specific operations framework. The contents of CPUECTLR_EL1 are
dumped currently.

This patch adds CPU core and cluster power down sequences to the CPU specific
operations framework introduced in a earlier patch. Cortex-A53, Cortex-A57 and
generic AEM sequences have been added. The latter is suitable for the
Foundation and Base AEM FVPs. A pointer to each CPU's operations structure is
saved in the per-cpu data so that it can be easily accessed during power down
seqeunces.

An optional platform API has been introduced to allow a platform to disable the
Accelerator Coherency Port (ACP) during a cluster power down sequence. The weak
definition of this function (plat_disable_acp()) does not take any action. It
should be overriden with a strong definition if the ACP is present on a
platform.
